javascript - 有没有办法可以使用 CKEditor 随时随地修改 MS Word 文档并将其保存在我的服务器中的某个位置

Question

我的要求是制作一个自定义文档库，我可以在其中保存带有版本的文档。

有没有办法可以使用 CKEditor 随时随地修改 MS Word 文档(.doc 或 .docx)并将其保存在我的服务器中的某个位置？

有关任何其他选项的建议也是可以接受的。

Answer 1

我不确定 .doc，但对于 .docx，您可以通过以下方式将其转换为 html...

您应该为此实现 OpenXml dll。 您需要的 dll 是

<强>1。 DocumentFormat.OpenXml.dll

<强>2。 OpenXmlPowerTools.dll

<强>3。 System.IO.Packaging.dll

这是代码片段的工作版本。 DocxToHtml.cs 类

    using System.IO;
    using System.Linq;
    using OpenXmlPowerTools;
    using DocumentFormat.OpenXml.Packaging;
    using System.Drawing.Imaging;
    using System.Xml.Linq;

     public class DocxToHtml
{

    public string ConvertToHtml(string fullFilePath)
    {
        if (string.IsNullOrEmpty(fullFilePath) || Path.GetExtension(fullFilePath) != ".docx")
            return "Unsupported format";

        FileInfo fileInfo = new FileInfo(fullFilePath);

        string htmlText = string.Empty;
        try
        {
            htmlText = ParseDOCX(fileInfo);
        }
        catch (OpenXmlPackageException e)
        {

            if (e.ToString().Contains("Invalid Hyperlink"))
            {
                using (FileStream fs = new FileStream(fullFilePath, FileMode.OpenOrCreate, FileAccess.ReadWrite))
                {
                    UriFixer.FixInvalidUri(fs, brokenUri => FixUri(brokenUri));

您所要做的就是向 ConvertToHtml 方法提供 .docx 文件的文件路径，它将为您完成工作并为您提供 html。

注意:这只支持.docx
